Help identifying headgear

i remember as i was levelling this mage, i equipped this headgear which was sort of a halo of jewels circling on top of my head. but i can't for the life of me remember what it's called..please post if you do know as i would like to transmog that piece
Circle of Flame? (Check the wowhead screenshots)
Are you looking for Tourmaline Crown? I'm currently using that as my transmog head piece and it sounds like what you're looking for.

Also quite rare - the Tourmaline Crown looks identical and is from a quest line in BC so costs nothing and is easily solo'd.
the piece i had was the crown of endless knowledge. but its the same design as the tourmaline crown so im gonna go do that quest for it.

thanks very much to you all.

by the way, since im trying to look for gear to transmog, i might as well ask about other slots. i remember when i was around level 60 or 70, my gear was such that i didnt look like a mage, more like a fashionista. i remember the chestgear was like a blue long sleeve shirt which wasn't a robe and that's important cause it doesn't drop down to my ankles and cover my trousers.

so if anyone has any suggestions on chestgear that isnt a robe and legpiece that looks like skinny jeans on the toon, please post it here.

ps. if you know of shouldergear that doesnt look like it belongs to WWF's legion of doom, something small, almost non-existent, please share as well.
ok. googled a little and found www.worldofwardrobes.net is a great place to DIY random pieces of gear
